External structural element e.g. ceiling, for external cladding of e.g. buildings, has heat pipe whose lower end is arranged as lower heat transmission unit in water body present below building

摘要

The structural element has upper heat transmission units (41) in a form of pipes or panels arranged at a surface of the structural element. The transmission unit is a component of a heat pipe (4). The surface is attached to a building, and a lower end of the heat pipe is arranged as a lower heat transmission unit (42) in a water body present below the building. An evaporator surface of the heat pipe is arranged in the water body and a condensation surface is arranged at the structural element.
